I remember when I was a kid, we used to play this game. I don’t remember what it was called, but it went something like this:
One person says, “Infiniti”, the other says, “Infiniti +1”, the first person says “Infiniti+Infiniti”, the other one says, “InfinitixInfiniti”, and so and so forth, until one says a bigger number and the other gives up.
Now, in a very narrow, silly way, you could look at the ancient world as a variant of this game.
One person believes in the god of a tree, another believes in a god of the forest, another believes in a god of life, and so on and so forth.
An interesting aspect of this process, is that rather than go on forever, as the game I played as a kid could, this one reaches some limits.
It’s not possible to believe in anything more powerful than one god.
It’s not possible to believe in anything more evil than a devil.
It’s not possible to believe in a better fate than heaven.
It’s not possible to believe in a worse fate than hell.
And while this doesn’t imply much about the reality of the beliefs themselves, it does reveal that are some fundamental limits to the mind as to what is possible to conceive and believe.
